Abstract

Cathode Electrolyte Interphase

The cover illustrates the debate about the presence of cathode electrolyte interphase (CEI) in course of electrolyte oxidation in high voltage batteries, in particular dual ion batteries (DIBs). In article number 2400330 by Johannes Kasnatscheew and co-workers, graphite-based cathode active material (CAM) is free of transitions metals (TMs) and TM-related impurities, which simplifies research of CAM surface. In fact, no CEI indications are found, hardening CEI as “myth”.

用lipf6基非质子电解质研究双离子电池石墨上阴极电解质界面的存在及容量衰减的原因

本文介绍了高压电池，特别是双离子电池（dib）电解液氧化过程中阴极电解质间相（CEI）存在的问题。在Johannes Kasnatscheew等人的2400330号文章中，石墨基阴极活性材料（CAM）不含过渡金属（tm）和与tm相关的杂质，简化了CAM表面的研究。事实上，没有发现CEI的迹象，使CEI成为“神话”。
